@Gbowes if its only one room it sounds like you need a booster to improve the WiFi in thst room. However if you plan to game on a PS5 you msy want to consider a different solution as gaming or streaming over a poor wifi connection is going to be poor. Powerline adapters which use your home's mains cabling to carry the data could be a better solution.
